Mandatory Access Controls (MAC) like SELinux or TOMOYO allow you to create a policy that can deny access to files. The problem, and that's why I said it would probably be convoluted, is that it is unlikely that any existing policies will match your needs so
you'll have to write your own policy: tedious, bothersome and no guarantee your policy works until you have tested it. If you want to learn more best read the documentation first.

switch_root
SWITCH_ROOT(8) System Manager's Manual SWITCH_ROOT(8)
NAME
switch_root - switch to another filesystem as the root of the mount tree.
SYNOPSIS
switch_root [-hV]
switch_root newroot init [arg...]
DESCRIPTION
switch_root moves already mounted /proc, /dev and /sys to newroot and makes newroot the new root filesystem and starts init process.
WARNING: switch_root removes recursively all files and directories on the current root filesystem.
OPTIONS
-h, --help
show help and exit
-V, --version
show version number and exit
RETURN VALUE
switch_root returns 0 on success and 1 on failure.
NOTES
switch_root will fail to function if newroot is not the root of a mount. If you want to switch root into a directory that does not meet
this requirement then you can first use a bind-mounting trick to turn any directory into a mount point:
mount --bind $DIR $DIR
SEE ALSO
mount(8) chroot(2) init(8) mkinitrd(8)

AVAILABILITY
The switch_root command is part of the util-linux-ng package and is available from ftp://ftp.kernel.org/pub/linux/utils/util-linux-ng/.
